Dell Zino Wireless N 1520 - Drivers not working

I am having the same problem (for 3 weeks)... try running NetMeter and see what the throughput looks like for the wireless connection.

My connection never dropped out, but my throughput ramped up and then down to nearly zero every 10-15 seconds, even though I consistently had a 162-234Mbps readout in the windows wireless network dialog box. Since I went in and "disabled 802.11a" in the adapter settings, I can connect on the 2.4GHz band flawlessly at 54Mbps, no ramps up and down (I set my router to limit at 54Mbps)... but I am no closer to running at 300Mbps on the 5GHz band.

I have dual posted about it on another website (smallnetbuilder)... let me know what you get!

I figured it out...

If anyone is having streaming video problems, stutter, choppy, etc. with the Dell Zino HD (Inspiron 400) or just strange/variable wireless throughput, turn off and disable the "Advanced Networking Service" or do a clean installation of your OS.

After 3 weeks I figured out that some of the Dell installed software "Remote Access" uses this service and my theory is that the Dell software periodically screws up the wireless throughput. After you disable the service, on your next restart, some notification box will pop up telling you that the Dell software can't run without this service -- I have just been ignoring it, but I assume if you uninstall the Dell software, it will go away. Note: I did try uninstalling all the Dell software FIRST, but that did not seem to solve the throughput/pulse train problem.

FYI, my system has the DW1520 card and I am operating in wireless n.
